construction that has been especially designed for autoim'xbiles "and other vehicles.

The. primary object of our invention is to provide positive and reliable means, in a manner hereinafter' set forth, for easily and quickly attaching a. demountable rim` to the fixed rim of a wheel, whereby the rim and the tire carried thereby can be placed in position with the use of a single tool and in a manner that prevents accidental displacement of the rim and tire when the wheel is in operation.

A further object of our invention is to provide a deinountable rim in the general make up of 'which the parts are constructed with a view of reducing the cost of manutactureand 'at the saine time retain the fea.- tures by which safety, durability, slmplicity and of assembling are secured, and with such ends in View, our invention resides in the novel construction, combination and arrangement of parts to he hereinafter specifically described and then claimed.

lieferencetwill now be had to the drawings, wherein there are illustrated the preyterred embodiments of our invent-ion, but 4it is to be understood that'the structural elements to be hereinafter referredl to are susceptible to such changes, asl in the size, shape` and manner of assemblage, as fall .vithinsthe scope of the appended claims.

ln the drawings-Figure 1 is a side elevationlof a portion of a wheel provided with a demountable rim in accordance with our invention; Fig. 2 is an enlarged side elevation of a portionv of a demountable rim and fixed rim, with the fastening means thereof removed; Fig. 3 is a cross sectional View of the same showing the fastening means in position; Fig. 4 is a plan of the same partly broken away; Fig. 5 .is a Similar View illustrating a modicationof our invention; and Fig. 6 is a cross sectional. view of the same.

Referring first to Figs. 1, 2 and 3, the reference numeral 1 denotes a fixed wheel rim that is channel shaped and to which the spokes 2 of a hub 3 are connected. The outer wall 4 of the fixed rim is provided with spaced openings 5 formed by cutting..

away the outer edge of the wall to a depth I that will allow of the bottom of the opening 5 being flush with the bottom of the channel :formed by the fixed rim. The inner wall s u" b of the nxcd run has spaced enlargements 7 l at pointe opposite thevopenings 5 and said enlargements are provided with openings 8 registering with openings .l in the wall 6 of the fixed rim. The walls of the openings 8 are screwthreaded and the enlargements' 7 'serve fnnctionallyras stationary nut-s and mayfbe of such form, brazed or otherwise' secured to' the outer side Lof the fixed rim wall 6. Y

The reference numeral 10 denotes a demountable rim provided with peripheral clencher edges or -ianges l1 adapted to retain a conventional form of tire case'or tire upon the rim, and the inner side of said rim has spaced lugs or blocks 12 adapted to eX- tend transversely of the fixed rim 1 with one end abutting the wall 6 and the oppositeend closingthe opening 5 of the wall i. The lugs or blocks 1f?, are rectangular in plan and are welded or otherwise secured to the rim 10. Each block has a longitudinal bore orope-ning 13 registering vwith the openings 9 and S of the wall '6 and enlargements 'i' respectively. The outer end of the lug or block completely fills the opening 5 of the 'wall l and arrangedagainst saidwall and theend of the lug or block12 is an angle clip 111 provided withan openingl registeringwith the outer: end; ofthe bore, 13. Extending" through the opening 15, the' bore 13 and the opening 9 into the threaded open-y .;zftending under the fixed rim without inter- 10,

ltering with the spoke connections thereof. The clips 14 strengthen or reinforce the wall 4 adjacent the --openings 5 and serve practically as a wall, whereby the lugs or blocks 1,54 12 can. beffirmly anchored relative to the firmer Wall 6 of the fixed rim.

pj-Reference willnow be had to Figs. 5 and 6g illustrating -a modification of our invention, and instead 4of providing the outer side ,olthe'inner wall `6 of the fixed rim 1 with anenlargement 7, the inner side 'of said wall ,'-isfprovided with a stationary enlargement riveted or otherwise secured to said x,ed rim against Ithe wall 6. The enlarge .'ment19a`nd the wall 6 of the'fixed rim are yprovided withregistering openings 21 having the walls thereof screwthreaded, and the outer end of the enlargement 19 .has a :tapering or wedge shaped recess 22 adapted to receive the inner end of the tapering or ,wedge shaped lug or block 23 riveted or otherwise secured to a rim 20. The outer end of the lug or block V23 fits in the ope'n- 4Vfing 5 of the wall 4 of the fixed rim and associa-ted withgsaid lug or block is a. 'clip 24 A.and a screw bolt 25. The screw bolt 25 ex- "tends through the clip 2,4rand the bore or openings 26.' of the lug or block and is screwed into Vthe: threaded openings 21. The lshape of the lug or block 23 permits of said lug or block andthe enlargement 19 being -drawn together b v theescrew bolt 25, wherebv the rim 20 and the angle clip 24 Will be firmly held bv the fixed rim 1 of the wheel.

- mountable rim can be removed from theA The" rim 20 bears upon the walls 4 and 6 of thefixed rim 1 and is held against lateral and vertical displacement, without any danger of the rim shifting during the use of the v wheel.

From .theforegoing it willbe observed vthat without muchexertion or labor a defixed j rim of the wheel, particularly'when a tire has been punctured or otherwise 1njured and it is necessary' to substitute anrim, a riin, lugs carried by said rim and extending-into said channel fixed rim, enlarge- -ments carried by a Wall of said fixed rim,

clips engaging the other wall of said fixed rim and ends of said lugs and extending under said fixed rim, and means extending through said clips longitudinally of said lugs and engaging said enlargements for holding said rim upon said fixed rim.

2. In a demountable rim, a channel fixed rim having the outer wall thereof provided with openings, enlargements at the inner wall of 'said ehannel= fixed rim, a rim, lugs carried by said rim and extending into said channel fixed rim with the outer ends of said lugs filling the openings of the outer wall of said fixed rim, angle clips against the outer wall of`\said fixed rim and extending under said fixed r1m,and screw bolts extending through said angle clips, said lugs, 'and into the enlargements of said channel fixed rim.

- 3. In a delnountable rim, a channel fixed rim,-enlargements against the outer side of the inner wall of said channel fixed rim, a rim, lugs carried by said rim and extending into said' channel fixed rim with the inner lends thereof abuttingthe inner wall of said fixed rim and the outer ends thereof extending into the outer wall of said fixed rim. clips of larger area than the outer ends of said lugs arranged against the outer wall of said fixed rim and extending under said fixed rim, and screw bolts extending through said clips longitudinally of said lugs and into the enlargements of said fixed rim for maintaining said rim upon the walls ofl the fixed rim.

In testimony whereof we affix our signatures in presence of two witnesses.
